I NITED STATES PATENT WILLIAM J. WICKES AND LUDWIG BAKER, OF SAGINAIV,MICHIGAN.

UPRIGHT ATER-TUBE BOILER.

SPECIFICATION forming part of Letters Patent No. 604,509, dated May 24:,1898.

Application filed October 4, 1897.

To aZZ whom it may concern:

Be it known that we, \VI LLIAM J. WVICKES and LUDWIG BAKER, of Saginaw,Michigan, have invented certain new and useful Improvements in Upright\VateuTube Boilers, of which the following is a specification.

This invention relates to steam-boilers of the upright water-tubevariety, and has for its object to provide a boiler of this class havinga high efficiencyata low cost for construction and maintenance.

To this end the invention consists in a watertube boiler comprising asuitable easing or' setting having a transverse vertical partitiontherein, a fire-chamber communicating with the heatingspace 011 one sideof said partition and an outlet for the spent gases on the other sidethereof, front and rear sets of vertical tubes arranged,respectively,onopposite sides of said partition, a drum connecting the lower ends ofsaid sets, a steam-drum connecting the upper ends of said sets, and abaffle-plate in said steam-drum extending over the set of tubes on thatside of the partition into which the fire-chamber opens, whereby thewater in the tubes of said last-mentioned set will be prevented frombeing thrown up into the steam-space in said drum and the steam willthereby be kept and delivered dry.

In the accompanying. drawings, Figure 1 is an e1evation,partly brokenaway, of the boiler, the setting being shown in vertical sections. Fig.2 isa transverse section taken on the line 2 2 of Fig. 1. Fig. 3 is anenlarged view, in vertical section, of the upper portion of the boiler;and Fig. 4. is a transverse sectional view taken on the line 4. 4. ofFig. 3.

In the said drawings,A represents the boilersetting, which may be of anyapproved type and which is constructed to provide the furnace orfire-chamber B and the boot 0, from which rises the stack D. Within thesetting and supported upon a cast-iron ring E is the broiler proper,comprising a lower head or mud-drum F and an upper head or steamdrum G,which are connected by two sets of tubes 11 and H, which will behereinafter designated, respectively, as the front and rear sets.

I indicates a partition extending vertically upward from the lower drumF to a point some distance below the steam-drum G and Serial No.654,003. (No model.)

also extending transversely from one side of the setting to the other,as shown in Fig. 2. The waterline is indicated at J and above saidwater-line there is located in the steamdrum G a baffle-plate K, whichextends over the front set of tubes H, which receives the products ofcombustion from the firechamber B. Thisbaffle-plate is preferablyhinged, as indicated at 70, to the braces or stays g of thesteam-drum,and in practice we prefer to make said baflie-plate in twosections, as shown in detail in Figs. 3 and 4., there being provided astationary section is, adjacent to the wall of the steam-drum, and ahinged section 7 0 arranged slightly above and extending from a pointsomewhat over the stationary section to the center of the steam-drum,where it is hinged, as hereinbefore set forth. The free end of thebafiie-plate rests upon suitable lugs L, secured to the braces or staysg and to the wall of the steam-drum,and is secured in position by meansof pins M,which pass through suitable apertures in the plate and arethemselves slotted to receive locking-wedges N.

The baffie-plate K is preferably given a slight inclination upwardtoward the central portion of the steam-drum, as clearly indicated inthe drawings.

In boilers of the type herein described the set of tubes on that sideofthe partition adj acent to the fire-chamber receive the products ofcombustion and heated gases directly from said chamber, and the water insaid tubes is subjected to a high degree of heat, and steam is quicklyproduced. The tubes on that side of the partition adjacent to the stackare not so highly heated, and a circulation of water is thus produced upthe front set of tubes and down the rear set of tubes, thus exposing allof the water successively to the action of the greatest heat and therebyincreasing the efficiency of the boiler. NV e have found, however, thatthe heating action in the front set of tubes is sometimes so great thatthe water in said tubes is thrown out upward therefrom, and ifunobstructed rises into the steam-space above the water-line in thesteam-drum and thus tends to saturate the steam, making it difficult toobtain dry steam from the boiler. By reason of the construction which wehave devised the baffie-plate located above the front set of tubesserves to prevent the water from said tubes from rising into thesteamspace and deflects the water downward and rearward toward the rearset of tubes, thus increasing the efficiency of the circulation in theboiler. We prefer to employ a hinged baffle-plate, for the reason thatsaid plate when hinged may be lifted up into the position shown indotted lines in Fig. 3 for the purpose of giving access to the front setof tubes in order that they may be inspected and cleaned. Byconstructing the baffleplate when hinged in two sections, the hingedsection overlapping and arranged above the fixed section, the free edgeof the hinged section is rendered more accessible for the purpose ofraising and lowering the same.

It is obvious that various modifications in the details of constructionmay be made without departing from the principle of our invention. Forinstance, although we have shown a casing and boiler circular insection, it is obvious that they may be rectangular, polygonal, or ofother form. The mud-drum will of course be provided with a suitableblow-off, such as is indicated at F, and with one or more manholes O.The steam-drum will be provided with suitable manholes G, and thesetting or casing will be provided with suitable clean-out openings P.We therefore do not Wish to be understood as limiting ourselves to theprecise details of construction shown in the drawings and hereinbeforedescribed.

We claim 1. An upright water-tube boiler comprising a suitable settingor casing having a transverse partition therein, a fire-chambercommunicating with the heating-space on one side of said partition andan outlet for the spent gases on the opposite side of said partition,front and rear sets of tubes arranged respectively on opposite sides ofsaid partition, a drum connecting the lower ends of said sets, asteam-drum connecting the upper ends of said sets, and a baffle-plate inthe steam-drum extending over the front set of tubes only, substantiallyas described.

2. An upright water-tube boiler comprising a suitable setting or casinghaving a transverse partition therein, a fire-chamber comn1 unicatingwith the heating-space on one side of said partition and an outlet forthe spent gases on the opposite side of said partition, front and rearsets of tubes arranged respectively on opposite sides of said partition,a drum connecting the lower ends of said sets, a steam-drum connectingthe upper ends of said sets, and a baffle-plate in the steam-drumextending over the front set of tubes only and hinged to permit accessto said tubes, substantially as described.

3. An upright water-tube boiler comprising a suitable setting or casinghaving a transverse partition therein, a fire-chamber communicating withthe heating-space on one side of said partition and an outlet for thespent gases on the opposite side of said partition, front and rear setsof tubes arranged respectively on opposite sides of said partition, adrum connecting the lower ends of said sets, a steam-drum connecting theupper ends of said sets, and a baffle-plate in the steam-dru n1extending from the wall of the drum inward in an upwardly-inclineddirection over the front set of tubes only, substantially as described.

4. An upright water-tube boiler comprising a suitable setting or casinghaving a transverse partition therein, a fire-chamber communicating withthe heating-space on one side of said partition andan outlet for thespent gases on the opposite side of said partition, front and rear setsof tubes arranged respectively on opposite sides of said partition, adrum connecting the lower ends of said sets, a steam-drum connecting theupper ends of said sets, and a baffie plate arranged in the steam-drumextending over the front set of tubes and comprising a fixed sectionadjacent to the wall of the drum and a hinged section located above thefixed section and extending therefrom inward to the central line of thedrum, substantially as described.
